Activity detection in web applications

ABSTRACT

A computing system includes a web server, client computing devices, a proxy between the web server and the client computing devices, and an analytics server. Each client computing device is operated by an end-user to access an application based on end-user events resulting in representational state transfer (REST) calls to the web server. The proxy passes through the REST calls to the web server and returns responses from the web server, with the return responses corresponding to activities being performed within the web application. The analytics server correlates the end-user events with the corresponding REST calls and return responses from the proxy for each client computing device, and uses vectorization to compare similar activities. The analytics server associates the similar activities with a quality indicator to identify anomalies within the application for corrective action to be taken.

TECHNICAL FIELD

The present disclosure relates to web applications, and more particularly, to analyzing activities performed within an application across a large set of end-users.

BACKGROUND

Software as a Service (SaaS) is a computing approach to software delivery by which applications are centrally hosted on one or more third-party servers (e.g., in the cloud) and are typically provided on a subscription basis to users. SaaS applications are offered for numerous areas, including business, accounting, and even gaming applications.

SaaS applications are typically accessed on client computing devices via an internet browser. A large set of end-users within an enterprise may access the same SaaS application, where each end-user causes the SaaS application to perform various activities.

Many of the activities performed within the application are similar across the large set of end-users. Since SaaS applications are on third-party servers, it is difficult for an enterprise to monitor activities of their end-users within a SaaS application since the enterprise does not own the server providing the SaaS application.

SUMMARY

A computing system includes a web server to provide an application and client computing devices. Each client computing device is operated by an end-user to access the application based on end-user events resulting in representational state transfer (REST) calls to the web server. A proxy is between the web server and the client computing devices, and is configured to pass through the REST calls to the web server and to return responses from the web server, with the return responses corresponding to activities being performed within the application.

An analytics server is configured to receive the end-user events from each client computing device, and to receive the REST calls and the return responses from the proxy. The analytics server comprises a processor configured to correlate the end-user events with the corresponding REST calls and return responses from the proxy for each client computing device, and translate respective correlated end-user events, REST calls and return responses into respective event vectors. The analytics server processes the respective event vectors to determine similarities among the client computing devices, with the similarities corresponding to similar activities, and associates the similar activities with a quality indicator to identify anomalies within the application for corrective action to be taken.

The quality indicator may be based on one or more statistics associated with the end-users accessing the application. The corrective action may comprise recommending to one or more end-users which end-users events to use for more efficiently performing a particular activity within the application.

Processing the respective event vectors by the processor may comprise placing the respective event vectors in sequence for each client computing device, and selecting an n-set of event vectors in sequence from the sequence of event vectors for each client computing device, where n>1. An activity within the application corresponds to the selected n-set of event vectors in sequence. A composite activity vector is generated by adding together the event vectors in the n-set of event vectors in sequence for each client computing device. The composite activity vectors for each client computing device are placed in vector space. The similarities among the client computing devices are determined based on similarities between the composite activity vectors among the client computing devices.

Each client computing device comprises an embedded browser to monitor the end-user events by capturing events at the document object model (DOM) level within a web page.

Each client computing device comprises a processor configured to cooperate with the embedded browser to extract end-user event attributes from the DOM, with the end-user event attributes providing contextual information on the corresponding end-user event. The analytics server receives the contextual information associated with the end-user events, and is further configured to include the contextual information in the respective event vectors.

The corresponding REST calls and return responses from the proxy include parameter information noise, and where the analytics server is further configured to remove the parameter information noise by applying one or more reducer functions. Applying the one or more reducer functions comprises translating each event vector into one or more reduced event vectors, with the resulting reduced event vectors being used as the event vectors by the analytics server.

The n-set of event vectors in sequence corresponds to a pattern that includes a beginning and an end of the corresponding activity. The analytics server is further configured to incrementally vary n for the n-set of event vectors, generate an activity vector for each value of n, examine each activity vector for a pattern, and select the n corresponding to the activity vector having a pattern.

Another aspect is directed to a method for operating an analytics server within a computing system as described above, with the method comprising receiving the end-user events from each client computing device, receiving the REST calls and the return responses from the proxy, correlating the end-user events with the corresponding REST calls and return responses from the proxy for each client computing device, and translating respective correlated end-user events, REST calls and return responses into respective event vectors. The method further includes processing the respective event vectors to determine similarities among the client computing devices, with the similarities corresponding to similar activities, and associating the similar activities with a quality indicator to identify anomalies within the application for corrective action to be taken.

Yet another aspect is directed to a non-transitory computer readable medium for operating an analytics server as described above, and with the non-transitory computer readable medium having a plurality of computer executable instructions for causing the analytics server to perform steps as described above.

Nos. 9,176,744 and 9,538,345, which are incorporated herein by reference in their entirety. The '744 and '345 patents are both assigned to the current assignee of the present disclosure.

Referring initially to FIG. 3, the illustrated computing system 10 includes client computing devices 20(1)-20(n), a web server 40 providing an application 42, a proxy 50 and an analytics server 60. The proxy 50 is positioned between the client computing devices 20(1)-20(n) and the web server 40. The analytics server 60 is in communications with the client computing devices 20(1)-20(n) and the proxy 50, and analyzes activities within the web application 42 as initiated by end-users of the client computing devices 20(1)-20(n).

As will be discussed in detail below, the analytics server 60 analyzes sequences of representational state transfer (REST) calls related to end-user tasks. Similar activities among the end-users are detected using vectorization techniques, with the similar activities being associated with quality indicators to identify anomalies across the end-users.

The quality indicator may be based on one or more statistics associated with the end-users accessing the application 42. Corrective action may be directed to quality improvement recommendations, for example, for end-users that are not as efficient in performing similar activities within the application 42 as compared to other end-users. As such, the systems and methods set forth herein advantageously provide improved performance within a virtualized and/or enterprise computing environment.

The client computing devices 20(1)-20(n) are generally referred to as client computing devices 20 and typically operate within an enterprise. Each of the end-users of the client computing devices 20(1)-20(n) access the same application 42 within the web server 40.

The number of computing devices 20 may vary from several hundred to several thousand, for example. The statistical data tends to be more accurate for larger sets of client computing devices 20. Statistical data may include calculation of standard deviations for the end-users operating the client computing devices 20 for performing particular activities within the application 42. Statistical data may also include calculation on the frequency and speed of performing particular activities within the application 42.

Each client computing device 20 includes an embedded browser 24 to access the application 42. The embedded browser 24 is a browser embedded within a native application 22. For example, Citrix Receiver and Citrix Workspace App are programs that are installed on client computing devices 20.

Since the embedded browser 24 is embedded within the native application 22 within the client computing device 20, this allows end-user events to be collected. End-user events include mouse clicks and key strokes, for example. One or more input devices 26 coupled to the native application 22 are used to generate the end-user events. A mouse and keyboard are example input devices 26.

More particularly, the end-user events are collected at the document object model (DOM) level within a web page. This advantageously allows attributes associated with the end-user events to be extracted from the DOM. Example attributes include the label of a button that has been clicked, page titles and the likes. Attributes may be used to provide contextual information corresponding to the activities being performed within the application 42. Each client computing device 20 provides end-user events and their corresponding attributes to the analytics server 60.

As readily appreciated by those skilled in the art, most applications are driven by representational state transfer (REST) services, where each end-user request results in one or more REST calls to the web server 40. Activities are performed within the application 42 in response to the received REST calls.

REST is a web design model used by many cloud service providers, enterprises, and social media companies to define interfaces with their services. A cloud service provider may offer scalable computing resources as services over networks, such as provisioning virtual machine instances which can run enterprise applications for customers. Many cloud storage service providers use REST to define data integration APIs that may be invoked to extract and load data, among other things.

Web services that conform to the REST architectural style, termed RESTful web services, provide interoperability between computer systems on the Internet. RESTful web services allow the requesting systems to access and manipulate textual representations of web resources by using a uniform and predefined set of stateless operations.

The web server 40 providing the application 42 is typically not owned by the enterprise. This is particularly so when the web server 40 is a Software as a Service (SaaS) server, and the web application 42 is a SaaS application. Consequently, the enterprise does not have access to the web server 40 for installing equipment to monitor activities within the application 42 across each of the client computing devices 20.

Instead, the illustrated computing system 10 includes a proxy 50 for listening to server requests and responses from the server 40. It appears that the client computing devices 20 are communicating directly with the web server 40, but the client computing devices 20 are actually communicating with the proxy 50.

The proxy 50 is forwarding the REST calls to the web server 40 and then collects the results to send back to the client computing devices 20. Since the proxy 50 is acting as a man-in-the-middle, the proxy 50 is able to forward the REST calls and the return responses to the analytics server 60.

As will now be discussed in greater detail, the analytics server 60 is configured to analyze sequences of REST calls related to end-user tasks for each client computing device 20. For discussion purposes, the illustrated application 42 is SalesForce. SalesForce is a customer relationship management (CRM) application provided by SalesForce.com, Inc.

An example activity within the application 42 is when an end-user goes from a log-in page to a particular customer in SalesForce. This activity is based on a series of end-users events. The end-user events may be different for different end-users. For example, end-users may use a different number of key strokes or mouse clicks to go from the log-in page to a particular customer. As an example, to get to a particular customer one approach involves using a single mouse click and another approach is to use a couple of keystrokes, such as command C to go to a customer.

Most applications, such as SalesForce, have customization levels and data submitted in each REST call that is likely to be different for each request. Detecting similar sequences related to an activity cannot be performed on simple compares of REST calls. It is also difficult to detect the beginning and end of an activity without control over the end-user environment (i.e., the web server 40).

The above limitations are overcome by the analytics server 60 communicating with the client computing devices 20 and with the proxy 50 via the network 104. The analytics server 60 includes a processor 62 and a memory 64. The memory 64 stores end-user events and associated contextual information as received from the client computing devices 20, and stores REST calls and return responses as received from the proxy 50.

The processor 62 correlates the end-user events with the corresponding REST calls and return responses from the proxy for each client computing device 20. The correlations also include the end-user's intent for each end-user event.

As noted above, the embedded browser 22 within each client computing device 20 monitors the end-user events by capturing events at the DOM level within a web page. The processor 28 within each client computing device 20 is configured to cooperate with the embedded browser 22 to extract end-user event attributes from the DOM, with the end-user event attributes providing contextual information on the corresponding end-user event, i.e., the end-user's intent. Example attributes include the label of a button that has been clicked, page titles and the likes.

The processor 62 within the analytics server 60 translates the respective correlated end-user events, contextual information associated with the end-user events, REST calls and return responses into respective event vectors for each client computing device 20. The REST calls and return responses may be referred to as REST services. An event vector may be represented as follows:

Event Vector=f(end-user event, contextual information, REST services)

The corresponding REST calls and return responses from the proxy 50 include parameter information noise, and the processor 62 is configured to remove the parameter information noise by applying one or more reducer functions. Parameter information noise refers to the parameter information contained within the REST services which can lead to a wide variety of vectors for end-users.

For instance, when end-users log-in and go to particular customers, the particular customers are different. One end-user goes to customer A and another end-user goes to customer C, for example. Since both end-users are going from the log-in page to a customer, it does not matter which customer. The common activity being performed within the SalseForce is the fact that end-users are going from the log-in page to a customer. Customer specifics is an example of parameter information noise.

One or more reducer functions are applied by the processor 62 to translate each event vector into one or more reduced event vectors. The reduced event vectors do not include the parameter information noise. A reduced event vector may be represented as follows:

Reduced Event Vector=R(Event Vector)

where R is the reducer function. Multiple reducer functions may be defined depending on the type of parameter information noise collected by the embedded browser 24.

A reducer function is based on skip-grams. Skip grams may also be referred to as k-skip-n-grams where it tries multiple variants (many) of skipping n events over a sequence of k events until it finds a better clustering of reduced vectors. Skip-grams reported for a certain skip distance k allow a total of k or less skips to construct the n-gram. As such, “4-skip-n-gram” results include 4 skips, 3 skips, 2 skips, 1 skip, and 0 skips.

All reduced end-user events are placed in sequence to collect end-user behavior for each client computing device 20. An activity may be defined by a common sequence of reduced event vectors across the end-users. Detecting activities is implemented by extracting n-sets of reduced event vectors from the sequence of events. An n-set of reduced event vectors is a subset of subsequent reduced event vectors in sequence, where n>1. An activity within the application corresponds to the selected n-set of event vectors in sequence.

Since it is difficult to detect the beginning and end of an activity, the value of n is selected using a sliding window. The value of n is to be selected so that the n-set of reduced event vectors in sequence corresponds to a pattern that includes a beginning and an end of the corresponding activity.

The processor 62 incrementally varies n for the n-set of event vectors, and generates an activity vector for each value of n. An activity vector may also be referred to as a composite activity vector since the reduced event vectors in the n-set of event vectors in sequence are added together for each client computing device 20. The processor 62 examines each composite activity vector for a pattern. In this example, the activity is going from a log-in page to a customer.

As an example, n may start at 2. The processor 62 generates a composite activity vector with 2 of the reduced event vectors that are in sequence and examines the composite activity vector for a common pattern. If a common pattern is not detected, then the value of n is incremented to 3 by the processor 62. The processor 62 now generates a composite activity vector by adding the next reduced event vector in sequence (i.e., n=3) and examines the composite activity vector for a common pattern. This process is repeated until a common pattern is detected, i.e., end-users going from a log-in page to a customer in SalesForce.

By having large volumes of these sequences the processor 62 is able to find common end sets and make a determination that this is apparently a pattern. There will be a series of reduced event vectors added together representing end-users going from a log-in page to a customer. At some point there is no more benefit to have n too large since commonality is lost.

The processor 62 keeps a history of the composite activity vectors for all of the subsets of the sliding window. Each of the composite activity vectors for each client computing device 20 are placed in vector space. Cosine calculations are performed by the processor 62 to detect similar activities across all users.

The similar activities are associated with a quality indicator to identify anomalies within the application 42 for corrective action to be taken. The quality indicator may be based on one or more statistics associated with the end-users accessing the application 42. The statistical data tends to be more accurate for larger sets of client computing devices 20.

Statistical data may include calculation of standard deviations for the end-users operating the client computing devices 20 for performing particular activities within the application 42. Statistical data may also include calculation on the frequency and speed of performing particular activities within the application 42.

An anomaly, for example, corresponds to an end-user taking too long to perform an activity as compared to the other end-users. In this case, corrective action includes recommending to the end-user which end-users events to use for more efficiently performing the activity. This recommendation may be automatically generated and provided to the end-user by the analytics server 60. Alternatively, the recommendation is provided by an administrator of the analytics server 60.

Another anomaly, for example, corresponds to an end-user performing an activity more frequently than the other end-users. For example, an end-user accesses a customer in SalseForce and then copies the retrieved customer information into a directory on their client computing device 20. If this end-user is doing this for an unusually large number of customers, as compared to the other end-users, then there could be a security concern. The administrator of the analytics server 60 will investigate to see if the end-user is stealing customer data.

Another anomaly, for example, may result in quality improvements to the application 42. For example, a large number of end-users access a customer and then delete a customer. These are separate activities performed by the end-users. It would be more efficient for these end-users to perform this access and deletion as part of the same activity. In this case, a request would be made to the administrator of the web server 40 to include this feature in their application 42.

Referring now to the flowchart 200 in FIG. 4, and generally speaking, a method for operating the computing system 10 will be discussed. From the start (Block 202), the method includes operating client computing devices 20 to access an application 42 at a server 40 based on end-user events resulting in REST calls to the server 40 at Block 204. A proxy 50 is operated at Block 206 to pass through the REST calls to the server 40 and to return responses from the server 40, with the return responses corresponding to activities being performed within the application 42. An analytics server 60 is operated at Block 208 to analyze sequences of REST calls related to the end-user events to compare similar activities across a large set of end-users accessing the same application 42. The method ends at Block 210.

Referring now to the flowchart 300 in FIG. 5, and generally speaking, a method for operating the analytics server 60 within the computing system 10 will be discussed. From the start (Block 302), the method includes receiving the end-user events from each client computing device 20 at Block 304, and receiving the REST calls and the return responses from the proxy 306 at Block 304. The end-user events are correlated with the corresponding REST calls and return responses from the proxy 50 for each client computing device 20 at Block 308. The method further includes translating respective correlated end-user events, REST calls and return responses into respective event vectors at Block 310. The respective event vectors are processed at Block 312 to determine similarities among the plurality of client computing devices, with the similarities corresponding to similar activities. The similar activities are associated with a quality indicator at Block 314 to identify anomalies within the application for corrective action to be taken. The method ends at Block 316.

Referring now to the flowchart 400 in FIG. 6, a more detailed flowchart for processing the respective event vectors in the flowchart of FIG. 5 will be discussed. From the start (Block 402), the processing comprises placing the respective event vectors in sequence for each client computing device 20 at Block 404, and selecting an n-set of event vectors in sequence from the sequence of event vectors for each client computing device 20 at Block 406, where n>1. An activity within the application 42 corresponds to the selected n-set of event vectors in sequence. A composite activity vector is generated at Block 408 by adding together the event vectors in the n-set of event vectors in sequence for each client computing device 20. The composite activity vectors for each client computing device 20 are placed in vector space at Block 410.
